PCA9655E

Remote 16-bit I/O Expander

for I²C Bus with Interrupt

The PCA9655E provides 16 bits of General Purpose parallel Input /

Output (GPIO) expansion through the I C−bus / SMBus.

The PCA9655E consists of two 8−bit Configuration (Input or

Output selection); Input, Output and Polarity Inversion (active−HIGH

or active−LOW operation) registers. At power on, all I/Os default to

inputs. Each I/O may be configured as either input or output by writing

to its corresponding I/O configuration bit. The data for each Input or

Output is kept in its corresponding Input or Output register. The

Polarity Inversion register may be used to invert the polarity of the

read register. All registers can be read by the system master.

The PCA9655E provides an open−drain interrupt output which is

activated when any input state differs from its corresponding input

port register state. The interrupt output is used to indicate to the system

master that an input state has changed. The power−on reset sets the

registers to their default values and initializes the device state

machine.
